Hopefully that question is clear enough, and hopefully this is just me being silly. When I boot into the Recovery Partition, go into Terminal, and run 'diskutil list', I get quite a few tiny and seemingly invalid disks (starting at /dev/disk2):

/dev/disk0

I ran 'diskutil info' on each of the disks and received the following output:

Some of the drives are mounted in familiar places (like /Volumes) and some of them are mounted in less familiar places (like /private/var). Nevertheless, I don't recall any of these drives showing up as mounted the first time I've had my Mac. Does anyone perhaps know why these disks show up and/or if I can remove them? Thanks!

    Do not attempt to remove them, they're basically RAM disks and are needed for recovery mode to function. See this previous answer. – Gordon Davisson Oct 20 '14 at 21:24

    @GordonDavisson thank you for your very quick response! I will leave the drives alone. It was more of what seemed like an aesthetics problem. – Jake Lee Oct 21 '14 at 4:57
